[1] Gross billings for a specific period, which is one of the Company's key operating data, is defined as the total amount of cash received for the sale of course packages and services in such period, net of the total amount of refunds in such period.

[2] An "active student" for a specified period refers to a student who booked at least one paid lesson, excluding those students who only attended paid live broadcasting lessons or trial lessons.

"We achieved healthy growth in the third quarter and once again outpaced our guidance in both net revenues and gross billings, driven primarily by our strategy to expand the reach of our K-12 mass-market one-on-one offering in non-tier-one[3] cities," said Mr. Jack Jiajia Huang, Founder, Chairman and Chief Executive Officer of 51Talk. "The prevalence of our core K-12 mass-market one-on-one offering has increased at a strong pace, growing 65.9% year-over-year and accounting for 78.2% of our total gross billings in the third quarter. Our strategic initiatives to further penetrate non-tier-one cities are also paying off. Non-tier-one cities made up 69.4% of our K-12 mass-market one-on-one gross billings in the third quarter, compared with 65.4% and 58.6% in the prior quarter and third quarter of 2017, respectively.

"The online education industry in China is ripe with opportunities. As our primary K-12 mass-market one-on-one programs become more pervasive in lower-tier cities, we expect our growth to continue to accelerate. This strategy enables us to reach key audiences in underserved markets as we continue to grow our business with best-in-class programs that are helping shape the online education industry," Mr. Huang concluded.

Min Xu, Co-Chief Financial Officer of 51Talk, added, "We further strengthened our business in the third quarter, achieving strong our gross billings and net revenues growth on a year-over-year basis. More students are benefiting from our online English lessons with the number of active students during the third quarter increasing 18.9% year-over-year to 210,000."

Net revenues for the third quarter of 2018 were RMB303.2 million (US$44.1 million), a 28.4% increase from RMB236.1 million for the same quarter last year. The increase was primarily attributed to an increase in the number of active students and, to a lesser extent, an increase in the average revenue per active student. The number of active students in the third quarter of 2018 was 210,000, an 18.9% increase from 176,600 for the same quarter last year.

Net revenues from one-on-one offerings for the third quarter of 2018 were RMB278.6 million (US$40.6 million), an 18.9% increase from RMB234.4 million for the same quarter last year. Net revenues from small class offering for the third quarter of 2018 were RMB24.6 million (US$3.5 million), compared with RMB1.7 million for the same quarter last year.

Cost of Revenues

Cost of revenues for the third quarter of 2018 was RMB109.6 million (US$16.0 million), a 21.6% increase from RMB90.2 million for the same quarter last year. The increase was primarily driven by an increase in total service fees paid to teachers, mainly due to an increased number of paid lessons.

Cost of revenues of one-on-one offerings for the third quarter of 2018 was RMB92.9 million (US$13.5 million), a 7.1% increase from RMB86.8 million for the same quarter last year. Cost of revenues of small class offerings for the third quarter of 2018 was RMB16.7 million (US$2.5 million), a 387.2% increase from RMB3.4 million for the same quarter last year.

Gross Profit and Gross Margin

Gross profit for the third quarter of 2018 was RMB193.5 million (US$28.2 million), a 32.6% increase from RMB145.9 million for the same quarter last year.

Gross margin for the third quarter of 2018 was 63.8%, compared with 61.8% for the same quarter last year.

One-on-one offerings gross margin for the third quarter of 2018 was 66.6%, compared with 63.0% for the same quarter last year. The increase was mainly attributable to a lower revenue mix from the Company's American Academy program, which has a lower gross profit margin. 51Talk's small class offering gross margin for the third quarter of 2018 was 32.0%, compared with a negative gross margin of 100.4% for the same quarter last year.

Operating Expenses

Total operating expenses for the third quarter of 2018 were RMB282.2 million (US$41.1 million), a 1.2% decrease from RMB285.7 million for the same quarter last year. The decrease was mainly the result of a decrease in product development and general and administrative expenses, partially offset by increases in sales and marketing expenses.

Sales and marketing expenses for the third quarter of 2018 were RMB184.2 million (US$26.8 million), a 10.2% increase from RMB167.1 million for the same quarter last year. The increase was mainly due to higher branding and marketing expenses, partially offset by the RMB18.6 million net effect of capitalization and amortization of certain sales and marketing expenses under the new accounting standard adopted on January 1, 2018 (please refer to the section in this news release titled "Impact of Recently Adopted New Accounting Standard"). Excluding share-based compensation expenses, non-GAAP sales and marketing expenses for the third quarter of 2018 were RMB182.7 million (US$26.6 million), a 10.2% increase from RMB165.8 million for the same quarter last year.

Product development expenses for the third quarter of 2018 were RMB45.6 million (US$6.6 million), a 25.9% decrease from RMB61.5 million for the same quarter last year. The decrease was primarily due to a decrease in the number of personnel.

Outlook

For the fourth quarter of 2018, the Company currently expects:

Net revenues to be between RMB286 million to RMB291 million, which would represent an increase of approximately 9.7% to 11.7% from RMB260.6 million for the same quarter last year;

Total gross billings to be between RMB481 million to RMB491 million, which would represent an increase of approximately 22.3% to 24.8% from RMB393.4 million for the same quarter last year. - Gross billings for the Company's one-on-one business is expected to be between RMB422 million to RMB432 million, which would represent an increase of approximately 15.1% to 17.8% from RMB366.7 million for the same quarter last year. - Gross billings for 51Talk's small class business is expected to be approximately RMB59 million, which would represent an increase of approximately 121.0% from RMB26.7 million for the same quarter last year.

Management Change

The Company also announced today the planned retirement of Mr. Jimmy Lai, Chief Financial Officer, effective January 1, 2019. Mr. Min Xu, co-Chief Financial Officer of the Company, will assume the role of Chief Financial Officer at that time.

Mr. Jack Jiajia Huang, Founder, Chairman and Chief Executive Officer of the Company, said, "On behalf of the Board of Directors and myself, I would like to thank Jimmy for his remarkable service as 51Talk's Chief Financial Officer. Over the course of his nearly four-year tenure, Jimmy led us from the ranks of operating as a private company through our successful public listing on the New York Stock Exchange. He has made many great contributions to our continued growth and we wish him the best in his retirement."

Impact of Recently Adopted New Accounting Standard

In May 2014, the FASB issued ASU No. 2014-09, "Revenue from Contracts with Customers (Topic 606)." On January 1, 2018, the Company adopted the Topic 606 new standard using the modified retrospective method. Under this method, the Company records adjustments to its fiscal 2018 opening balance sheet (as of January 1, 2018) to reflect the cumulative effect of the new accounting standard. The comparative information has not been restated and continues to be reported under the accounting standard in effect for those periods. The Company has completed the assessment of related adoption impact, including but not limited to accounting for incentives to customers, contract modification, contract cost and forfeitures of prepaid credits.

The Company is required to estimate the breakage, or the forfeiture of prepaid credits, and recognize the expected breakage amount as revenue in proportion to the pattern of credits consumed by the customers. Based on the Company's analysis of historical customer forfeitures of prepaid credits, the Company has concluded that no breakage should be recognized, upon adoption or in first three quarters of 2018. The adoption of Topic 606 does not have any material impact on the Company's revenue recognition for the first three quarters of 2018 and comparable periods. The Company will continue to update the estimate of expected breakage at each reporting date.

The new accounting standard primarily impacts the accounting of the Company's sales personnel expenses. Under the new accounting standard, certain sales commissions to the sales personnel and the sales agents as well as new customer referral cost are considered incremental cost of obtaining contracts, and therefore shall be recognized as an asset given that the Company expects to recover those costs. RMB118.9 million, RMB100.3 million, RMB82.7 million and RMB76.0 million of contract cost asset was capitalized in prepaid expenses and other current assets account as of September 30, 2018, June 30, 2018, March 31, 2018 and January 1, 2018, respectively. The adoption resulted in an incremental, net capitalization of RMB18.6 million of sales and marketing expenses for the third quarter of 2018. The asset that was recognized for costs to obtain contracts will be expensed ratably in future periods, along with the recognition of revenue of corresponding contracts.

In evaluating its business, 51Talk considers and uses the following measures defined as non-GAAP financial measures by the SEC as supplemental metrics to review and assess its operating performance: non-GAAP sales and marketing expenses, non-GAAP product development expenses, non-GAAP general and administrative expenses, non-GAAP operating expenses, non-GAAP loss from operations, non-GAAP income tax expenses, non-GAAP net loss, non-GAAP net loss attributable to ordinary shareholders, and non-GAAP net loss attributable to ordinary shareholders per share and per ADS. To present each of these non-GAAP measures, the Company excludes share-based compensation expenses. The presentation of these non-GAAP financial measures is not intended to be considered in isolation or as a substitute for the financial information prepared and presented in accordance with GAAP. For more information on these non-GAAP financial measures, please see the table captioned "Reconciliations of non-GAAP measures to the most comparable GAAP measures" set forth at the end of this press release.

51Talk believes that these non-GAAP financial measures provide meaningful supplemental information regarding its performance by excluding share-based expenses that may not be indicative of its operating performance from a cash perspective. 51Talk believes that both management and investors benefit from these non-GAAP financial measures in assessing its performance and when planning and forecasting future periods. These non-GAAP financial measures also facilitate management's internal comparisons to 51Talk's historical performance. 51Talk computes its non-GAAP financial measures using the same consistent method from quarter to quarter and from period to period. 51Talk believes these non-GAAP financial measures are useful to investors in allowing for greater transparency with respect to supplemental information used by management in its financial and operational decision-making. A limitation of using non-GAAP measures is that these non-GAAP measures exclude share-based compensation expenses that have been and will continue to be for the foreseeable future a significant recurring expense in the 51Talk's business. Management compensates for these limitations by providing specific information regarding the GAAP amounts excluded from each non-GAAP measure. The accompanying table at the end of this press release provides more details on the reconciliations between GAAP financial measures that are most directly comparable to non-GAAP financial measures.
